Abstract: An experiment was conducted at Student’s Experimental Farm, Department of Agronomy, Sindh Agriculture University Tandojam during Rabi 2000-2001. Seven treatments viz.T1(00-00-00) control,T2 (100-50-50 NPK),T3 (120-60-50 NPK),T4 (140-70-50 NPK), T5 (160-80-50 NPK), T6 (180-90-50 NPK) and T7 (200-100-50 NPK) were tested to assess the effect of fertilizer levels on the yield and yield contributing characters of wheat variety T.J.-83. The fertilizer levels of NPK (T6) recorded significantly maximum weight of 1000 grains (43.19 g), biological yield (10833.3 Kg ha-1) and grain yield (3930 Kg ha-1). Results suggested that the combinations of 160-80-50 and 180-90-50 NPK Kg ha-1 produced satisfactory grain yield of wheat and could be recommended as farmers guideline.
